Hokkyoku / K-K-K-K-Koizumi-san

After just being dumped by her boyfriend, Yū's friend Misa Nakamura follows Koizumi to a ramen shop and ends up picking its spiciest dish, Hokkyoku ramen. Taking a liking to the extremely spicy ramen, Misa lets out her frustration over her breakup and becomes friends with Koizumi. Later, Yū's other friend, Jun Takahashi, is asked to speak with Koizumi about her poor test results, which turns out to be because she was exhausted following a ramen pilgrimage. Hearing about all the peculiar flavors of ramen Koizumi has tried, Jun decides to try out a Pineapple Shrimp Salt ramen at a local ramen shop, finding she still loves ramen despite how it fogs up her glasses.
